ASSIGNORS TO SAID LOWJ KEROSENE QlL. ENGINE.

SPECIFICATION forming part of Letters Patent No. 744,822, dated November 24, 1903. Application filed December 16,1902. Serial No. 135,364. (No model.)

T0 at whom it may concern:

Be it known that we, WILLIAM W. TUoK, of Richmond Hill, Queens county, ABBOT AUGUSTUS LOW, of Horseshoe, St. Lawrence county, and AUGUST WASSMANN, of Halletts Point, Astoria, Queens county, State of New York, citizens of the United States, have invented certain new and useful Improvements in Kerosene-Oil Engines, of which the following is aspecification sufficient to enable others skilled in the art to which the invention appertains to make and use the same.

Our invention relates to Vaporizers for kerosene-oil engines; and it consists in the special construction of parts hereinafter described and claimed specifically.

' In the accompanying drawings, Figure 1 is a sectional elevation of the engine-cylinder and cylinder-head provided with ourimprovements. Fig. 2 is a side elevation of our improved vaporizing-bell, Fig. 3, an end View of the same; Fig. 4, a view of the under side of the same; Fig. 5, atransverse section upon plane of line 5 5, Fig. 2.

Referring to the drawings, A represents a well-known form of piston-cylinder closed by a cylinder-head B of peculiar construction. This cylinder-head B is'sub'stantially hemispherical in construction, affording a concave combustion-chamber O, which is surrounded above by a hemispherical water-jacket D,th us rendering the exterior of the head safe to the touch, accidental or otherwise.

The hemispherical combustion-chamber C is provided with inlet and discharge ports in the usual manner. An oil-injector E of any ordinary or Well known construction is arranged to precipitate oil in the form of a line jet into the combustion-chamber O, which 1atter is providedwith a vaporizer V to receive the impact of the jet of oil.

The main peculiarity of our new form of vaporizer V is that it is bell-shaped in form, the oil impinging against the concave interior surface of the bell, as indicated in Fig. 1. It is obvious that this vaporizing-bell V may be formed integral with the walls of the combustion-chamber C, if desired; but We prefer to form it separately and to hang it centrallyin the dome of the cylinder-head D by means of a screw-bolt or other mechanical expedient. The edge of the bell V is formed with an opening or recess 1) at one side to admit of the injection of the oil at an angle substantially as shown in Fig. 1. On the opposite side the edge of the bell is formed with a lateral extension v, projecting in the directionof the valve-ports.

o is an aperture formed in the vaporizingbell V, through which protrudes an igniting device of any suitable or desired construction for use in starting the engine until such time as the vaporizing-bell V'becomes sufficiently heated to ignite the succeeding charges of oil.

It will be noted that by our peculiar construction concave surfaces only are opposed to the expansive force of the gases generated by combustion, thus utilizing the full efiect of the explosion upon the piston-head in the most direct and concentrated manner.

What we claim as our invention, and desire to secure by Letters Patent, is-- 1. Inakerosene-oil engine, the combination with the piston;cylinder, of a hemispherical cylinder-head, the concave dome of which is provided with a bell-shaped vaporizer havinga recess upon its inner face and a diametrically-disposed lateral extension, substantially as set forth. I

2. Inakerosene-oilengine,thecombination with the piston cylinder and piston head formed with a combustion-chamber, of a concave vaporizer having an oil-receiving recess and an oppositely-disposed lateral extension and means for injecting oil against the concave surface of said vaporizer, substantially as and for the purpose set forth.

3. In akeroseneoil engine, the combination of the piston-cylinder, hemispherical cylinderhead formed with the dome-shaped combustion-chamber, a bell-shaped vaporizer suspended in said combustion-chamber and pr0- vided with a recess, and oppositely-disposed lateral extension and aperture for the reception of the igniting device, and means for injecting oil into the interior of the said bellshaped vaporizer, substantially as set forth.

4:- In a kerosene-oil engine, the combination of the piston-cylinder, the dome-shaped cylinder-head B, the bell-shaped vaporizer V,

formed with the recess 7), and the oil-injector E, set at an angle with relation to the bellshaped vaporizer V, so that the oil is injected thereinto through the opening 2;, of the bell, substantially as and for the purpose set forth.

5. In a kerosene-oil engine, the combination of the piston-cylinder A, the hemispherical cylinder-head.B,formed with the dome-shaped combustion-chamber O, the bell-shaped vaporizer V, formed with the lateral extension '0, and means for injecting oil into said vaporizing-bell, substantially as and for the purpose set forth.

6. In a kerosene-oil engine, the combination of the piston-cylinder A, the hemispherical cy1inder-head B, formed with the dome-shaped combustion chamber 0, the upper side of which is protected by the hemispherical Waterjacket D,the bell-shaped vaporizer suspended in the dome-shaped combustion-chamber O,

and means for injecting oil against the interior surface of the vaporizer-bell V, substantially in the manner and for the purpose set forth.
